The aerogenerator has advantages of simple structure and convenient use, effectively improves the whole performance of the aerogenerator, enhances efficiency, has energy saving, consumption reduction and environmental protection and is easy for popularization, etc.

Description

technical field [0001] The invention relates to a wind power generator, in particular to a magnetic levitation self-adjusting pitch vertical axis wind power generator. Background technique [0002] Wind turbines are classified according to the direction of the rotation axis, which can be divided into two types: horizontal axis and vertical axis. Horizontal axis wind turbines are developed and matured theoretically based on aircraft propellers, and are currently widely used. However, the design and manufacture of horizontal axis wind turbines are very complicated, and have: 1. The impeller occupies a large space and covers an area; 2. The requirements for the wind tower are high; 3. The impeller is not uniformly winded, especially the ones installed in the air The blades must also bear the huge positive pressure of the wind, so their cost is very high. The greater the power of a single machine, the greater its cost. This is one of the main factors why the price of wind power...

Problems solved by technology

However, if there are limited nails, there will be impacts, and the blades will be easily damaged under long-term, periodic and strong impacts.

[0005] At present, the most vertical-axis wind turbines using parallel connecting rods are Japan (study started in 2002), and the United Kingdom, Canada and other countries are currently under development. Most of the products in these countries use parallel connecting rods in the impeller design. , this method has high requirements on the output shaft of the generator, and the structure is relatively complicated, and there are many on-site installation procedures

In addition, from the perspective of mechanics, the greater the power of the H-type vertical axis wind turbine, the longer the blades, and the longer the distance between the center point of the parallel bar and the center point of the generator shaft, the worse the wind resistance will be.

At the same time, the traditional vertical axis wind turbine has to overcome the self-weight and friction of the transmission mechanism, and at the same time overcome the resistance caused by the self-weight of the generator rotor and the friction of the mechanical bearing, which increases the driving force of the transmission drive system and reduces the generator load. efficiency
